Questions.

Common questions about the County Data Lookup API.

Read the docs
Which plan fits 10,000 county lookups a month?
The Starter plan covers 20,000 county lookups each month, easily handling 10,000 lookups with half your credits to spare. Each lookup costs 10 credits, which works out to about $1.50 per 1,000 calls. The Free plan includes 20 lookups per month for testing.
Are cost of living, education, and health metrics included on the Free plan?
No. The Free plan provides baseline figures including average income, poverty rate, and life expectancy. Detailed breakdowns—such as age distribution, education levels, health indicators, ZIP code lists, geographic coordinates, and cost of living metrics—require any paid plan.
Can I query counties outside the United States?
No. County Data Lookup exclusively covers US counties. Every request requires both a valid two-letter US state code and the county name.
What kind of health and economic metrics are returned?
Paid responses return living wage calculations, annual housing, food, and medical cost estimates, alongside education levels and age brackets. Health metrics include obesity rates, smoking rates, uninsured percentages, violent crime rates, and average PM2.5 air pollution levels.
Can I display this county data in a commercial real estate platform?
Yes, as long as you subscribe to a paid plan. Commercial use is permitted within your own applications, customer dashboards, and research tools. You may not resell or redistribute the raw county data as a standalone product.
